GAS-METER.

Specification of Letters Patent.

l etented April 27', 1909'.

' Application filed September 15, 1908, Serial No. 453,150;

{ of New Jersey, have invented certain new and useful Improvements inGas-Meters, of which the following is a specification.

My invention/relates to a device for making a record or bill of theamount of gas which has passed through a meter, the object of theinvention being to provide in connection with a meter of the ordinarytype a device by means of which the local inspector of the meter,instead of reading the meter, I and making a record thereof for deliveryto. the office, will at once take a duplicate record from the recordingmechanisms, one of which will be presented to the consumer as a bill,and the other will be delivered by the inspector to the ofiice of thecompany.

One of the objects of my invention is the construction and arrangementof the mechanism for operating the recording disks whereby the powerincident to the slow motion of the meter shaft may be gradually storedup and at a giventime released to impart a quick motion' to therecording dis s.

Other features of construction and arrangement which characterize myinvention are pointed out with particularity in theclaims annexed to andforming a part of this specification. For a better understanding of myinvention however, and the advantages possessed by it, reference may behad to the aocompan ing drawings and descriptive matter in w ich I ha eillustrated and described one of the forms in which my invention may beembodied. v

In the drawings, Figure l is a plan view of a gas meter provided with myimprovement, the mechanism of the meter and re cording device beingshown in dotted lines. Fig. 21s a front elevation of the same. Fig. 3 aside elevation-and Fig. 4 a detached perspective view of the plunger,recording wheels and mechanism for operating the same.

Referring to the reference letters of the drawings A, is the body of themotor which is provided with an-inlet pipe A and 'a discharge pipe A Themechanism of the meter proper is of the conventional t pe having avertical shaft A rovided with a 5 worm A, which meshes wit a worm wheelA? on a shaft A, which latter carries a pointer of the small dial of theor registering device, one revolution of whicregisters the passage oftwo; cubic feet of gas through the meter.

The device forming the subject matter of my invention comprises a box orcasing B, mounted upon the topof the meter and provided with a hingedlidor cover B to permit of ready access to the Workingparts of thedevice. Between the partsB and B a slot B is found through which afolded sheet of paper constituting a duplicate bill head may be passedto be acted upon by the recording mechanism. The recording mechanismcomprises a series of counting wheels C, C C G and C mounted upon ashaft 0 and journaled within the casing BQ It is sufficient to statethat each of the countingwheels is provided with a ratchet wheel havinten teeth adapted to be operated upon y av suitable spring pressed pawl.The units wheel 0 is worked by a separate pawl D, While all the otherpawls (not shown) ride idly upon disks until a notch in one of the disksis reached when the awl drops into the notch and being of suiiicientwidth to cover the adjacent ratchet wheel on the second or tens wheel itturns it one revolution and similarly with the hundred and thousandwheels.

The numerals on the counting wheels C C etc., are preferably outlinedwith projecting oints for the purpose of perforating the fold ed stri ofpaper inserted between the counting w eels and a plunger G. When astripof paper is inserted in the aforesaid manner, the plunger G, is. presseddownward against the action of a spgrial spring S, and the projectingpoints will e pressed through the paper into openings in the bottom ofthe plunger and the perforated record thus obtained will show at oncethe cost to the consumer of the gas which has passed through themeter.

In order to place the device at all times in position to record andavoid damage to counting wheels and other arts of the mechanism bydepressing the p unger when said wheels are in the act of turning, it isnecessary to convert the extremely slow motion of the meter mechanisminto a quick motion for operating the counting wheels which I accomplishin the following manner. The ratchet mechanism E, comprises a ratchet 4lever E mounted loosely upon the shaft C, 1

Patent is:

i Is

t roller to the lower most point of'the cam the-vertica shaft A and wormA including comprising a series of operatively connected wheel directlyconnected to the first recordmg wheel of the series, aratchet-leverloosely hung to said shaft, a spring connected at one oneend of said lever being provided with a s iral spring S and the ot erwith the pawl 1?, and a cam lever F. The cam lever F, is slotted asshown at f, to straddle a cam shaft H, upon which is mounted a cam H anda gear wheel H and is provided at its lower extremity with a roller F,which is brought to bear upon'the surface of the cam by the spring S Thecam H is made in the form of a scroll cam having a gradually inclinedportion it, over which the roller F rides and an abrupt terminusindicated at h which enables the spring S to return the with a quickmovement. The cam-shaft H, is driven b a suitable train of gearing froma worm wheel A, mounted upon a shaft A, which carries a pinionA", toengage the gear wheel H p Having described my invention what claim asnew and desire to secure by Letters 1. A .device of the characterspecified,

recording wheels, a shaft therefor, a ratchet end to the short arm ofratchet lever and at the other to the frame of the device, a pawltogether with a cam lever connected to the long arm of the ratchetlever, a roller mounted upon'the cam lever and a cam adapted to engagesaidroller to operate the cam lever and the .attached ratchet leveragainst the action of said spring.

2. A device of the character specified comprising a series ofoperativelyconnected recording wheels, a shaftfor supporting therecording wheels, a lunger arranged above the're'cording whee s andadapted to be manually operated to press a strip of paper intoengagement with the recording wheels, a ratchet wheel connected to oneof the recording wheels, a ratchet lever journaled uplon the shaftsupporting the recording w eels and provided with a spring pressed pawladapted to engage the ratchet wheel,

a spring interposed between the frame of the device and one end of theratchet lever, 'a

cam lever connected to the other end of the ratchet lever and a camoperated from a main source of power and adapted tooperate the camlever.

V In testimony whereof I-afibr my signature in presence of twowitnesses.
